Klamath River Basin—Hydrology and Topography

University of California, Santa Cruz, and Southwest Fisheries Science Center

The map shows the Klamath River Basin topography, hydrology, and watershed boundaries used by the Coho Salmon Technical Recovery Team. Due to the area's unique topography, the Klamath River and its basin are sometimes referred to as "upside down" since the headwaters begin in a flat, high-altitude plateau then flow through forested mountains to reach the ocean as opposed to more traditional river systems that begin in snow-covered mountains, and flow out of the mountains onto a broad, flat plain before reaching the sea.

An inset map shows how the Coho Salmon Technical Recovery Team watershed boundaries and the Natural Resources Conservation Service (NRCS) water quality watershed boundaries differ.
